Transcript of Thermophile Bacteria

T H E R M O P H I L E R I A T C A B A thermophile is a type of microorganism that lives and thrives at relatively high temperatures (113 to 252 ˚F). For other kinds of bacteria, living in this temperature could kill or damage them.Thermophiles are found in various geothermal heated regions in the Earth, including deep-sea hydrothermal vents. Most thermophiles are archaebacteria, but those that are eubacteria are among the earliest bacteria. What does it eat? Many thermophiles have a simple diet. It is usually based on metals, gases and minerals from the hydrothermal fluid. For example, one kind of thermophile feeds on sulfur, hydrogen, and carbon dioxide. This is sulfur... This is glowing ultrapure hydrogen... This is a carbon dioxide molecule... How has it adapted to hydrothermal vent communities? Thermophiles contain enzymes that function at high temperatures. Some of these enzymes are used in molecular biology and in washing agents. What are specific characteristics of thermophiles? "Thermophile" is derived from the Greek: thermotita, meaning heat, and Greek: philia, love. Thermophiles grow at temperatures that would kill or damage other bacteria. They grow best at temperatures between 120˚F and 158˚F. They can't grow at 68˚F or below. They are grouped into either prokaryotes or eukaryotes. They were first discovered by a man named Miquel in 1879. He found them in soil, dust excrement ( ), sewage and river mud. They have molecules and cell membranes that retain their stability at high temperatures
